Stax Guitar Tuner Pedal LT-901 - Mini True Bypass Tuner Pedal

In this review the Stax Guitar Tuner Pedal LT-901 is evaluated as a compact, stage-ready tuner for electric guitar and bass. The bottom line: it is for players who need a fast, accurate tuner that can sit on a crowded pedalboard and deliver near-silent tuning on stage. The review finds the LT-901 stands out for its 1 cent strobe accuracy and clear LED/LCD readout, making it reliable for live gigs and quick backstage setups where precision and minimal signal loss matter most.

Key Features

• Chromatic range: Wide tuning coverage from A0 (27.5Hz) to C8 (4186Hz) allows tuning of standard and extended-range instruments without compromise.
• High precision: Fast strobe mode with +/-1 cent accuracy helps dial in exact intonation for recording or critical live work.
• True bypass: The pedal maintains transparent tone when disengaged so the tuner does not color the guitar signal on stage.
• Compact portability: Mini size and light weight make it easy to place on any pedalboard and carry for outdoor gigs.
• Clear display: Deluxe LED and LCD indicators give an easy-to-read visual guide for quick and confident tuning under stage lighting.
• Silent tuning mode: Dual channel operation mutes output while tuning so players can adjust quietly in front of an audience.

Who It's For

The LT-901 is ideal for gigging guitarists and bassists who need a small, accurate pedal tuner that fits tight pedalboards and provides stage-friendly silent tuning. Players who value signal integrity will appreciate the true bypass design that preserves tone when the tuner is off. Its fast strobe mode suits musicians who demand precise intonation for recording or lead work.

Casual players who mainly tune at home with clip-on tuners or smartphone apps might find the LT-901 more feature-rich than necessary, and those who require battery power in the pedal should note it is powered by an external DC 9V adapter not included in the package.
